AR concentrations in liver of trapped Rattus rattus (RR), Rattus norvegicus (RN) and Mus musculus (MM). Concentrations of total (A), first generation (B), and second generation (C) ARs are presented. AR concentrations were determined by LC-MS/MS as previously described47 First-generation AR = coumatetralyl + warfarin + chlorophacinone. Second-generation AR = bromadiolone + difenacoum + brodifacoum + flocoumafen + difethialone. The dashed line corresponds to the concentration of 1000 ng/g.
